An open biomass gas combustion engine

Abstract

An open biomass gas burner, characterized in that it includes a furnace body, the furnace body is provided with a furnace, the bottom of the furnace is provided with an automatic ignition device, and the lower part of the side wall of the furnace body is connected with the furnace. The upper part of the side wall of the furnace body is provided with a fire outlet in communication with the furnace, and a silo is provided above the furnace body; a feeding device is provided between the hopper and the furnace body, and the feeding device includes connecting the furnace body and the hopper The feeding pipeline is provided with a feeding impeller, the rotating shaft of the feeding impeller is perpendicular to the channel direction of the feeding pipeline, and the outer edge of the blade of the feeding impeller is close to the inner wall of the feeding pipeline and feeds the The channel of the pipeline is closed, and the outside of the feeding pipeline is provided with a stepping motor that drives the rotation of the feeding impeller. The gas combustion engine of the present invention has a compact structure and is convenient to use. Its silo is designed in an open type, and fuel can be added at any time during the combustion process, and it can burn different fuels such as biomass wood briquette fuel, straw briquette fuel, wood powder, and wood blocks. The prospects are bright.

Description

Technical field [0001] The present invention relates to a gasification furnace (that is, a combustible gas generating device), in particular to a biomass gas generating device, which is referred to herein as a biomass gas burner. Background technique [0002] The raw materials for the gas produced by the biomass gasifier are crop straws, forest waste, etc. This gas is a green new energy with strong vitality. However, the existing biomass gasifier has some shortcomings: 1. The existing biomass gasifier has a relatively large volume, complicated structure and high cost; 2. The existing biomass gasifier has relatively high fuel requirements , Most of them can only use a single granular biomass fuel; 3. The existing biomass gasifier has relatively high requirements on the tightness of the upper silo, and the silo must be sealed as much as possible during use, and it cannot be used during use. Open the silo sealing cover for a long time to add materials. If the seal is not tight, the...

However, the existing biomass gasifiers have some disadvantages in producing gas: 1. The existing biomass gasifiers have relatively large volume, complicated structure and high cost; 2. The existing biomass gasifiers have relatively high fuel requirements , most of them can only use a single granular biomass fuel; 3. The existing biomass gasifiers have relatively high airtightness requirements for the upper bunker, and the bunker needs to be sealed as much as possible during use, and cannot Open the silo sealing cover for a long time to feed, if the seal is not tight, there will be dangers such as gas explosion
